I present you the one-and-only, have-fun-while-working-overtime, snowflakes-all-over-your-Desktop screen, full source code Delphi application.

Here's the recipe to amaze yourself and your coworkers (time required: 15 minutes):

• Let there be a main form (name: "MainSnowFlake") in a Delphi application.
• Hide the main form from the user by setting "Application.ShowMainForm := False;"
• Remove the button from the TaskBar.
• Turn this "program" into a System Tray Application.
• Add one more form (name: "SnowFlakeForm") to the project, remove it from the "Auto-create forms" list.
• Add a label to the SnowFlakeForm. Use a font with snowflake images.
• Play with CreateParams to make this form transparent, top-most, with no title bar. So that only the snowflake "image" remains visible.
• Add a timer (TTimer) to the SnowFlakeForm and let it randomly move the form over the Desktop screen in the OnTime event.
• Add a popup menu for the MainSnowFlake form. Popup will feature an "Add snowflake" and an "Exit" item.
• When the application starts, randomly draw 10 (you pick the number) snawflakes all over the Desktop.
• Have fun while exploring the full source code.

Note: this is not a perfect application. It would be better to use an image of the snowflake to create a true transparent form. Yes, this would require some more coding ... and the deadline for your money-making-application is around the corner.
